Meeting topic

One role of the NASA Earth Science Data Systems Standards Process Group (SPG) http://www.esdswg.net/spg is to develop a growing list of stable, operationally ready standards; as well as a body of technical notes related to implementation of standards, including specifications and practices that could develop into standards.

The SPG is often called upon within NASA for information and advice regarding specs, standards, and practices that are likely to have a large impact on NASA's internal data management processes as well as on NASA's role as a partner to international activities such as CEOS and GEO/GEOSS.

The SPG traditionally chooses a topic of interest as a theme for a technical information exchange session at each of its meetings.

On Tuesday, July 7, 2009, at the University of California, Santa Barbara, the SPG will host a technical session to investigate the topic of web services as it relates to Earth science data management. Our goal is to investigate and provide answers to these questions:

  1. What is the current state of the art in web services in this context? Are there specifications, standards, or practices about which the SPG should be seeking out RFC submissions? State of the art might imply that there is not yet widespread operational use, but that such use is likely to occur in the future.
  2. What is being used in production environments? For those web service specifications and practices that are in widespread, operational use, which ones should be entered into the SPG process?
  3. What experiments and trials are being done using new ideas or new ways of using existing ideas? Are there activities that could be documented as tech notes so that potential adopters can be made aware of them?

Current leading-edge activities in this area suggest that existing OGC specifications and Service Oriented Architectures based on UDDI, WSDL, SOAP, etc. are mismatched with emerging architectural patterns such as REST. How can the SPG help discern a pathway that will enable construction of robust, interoperable data systems?

We would like to invite speakers knowledgeable about this topic in this context to present their work during a technical session, followed by a round table discussion answering the questions posed above.
